javascript-lodashHow can I use Lodash's isEmpty function in JavaScript?
The isEmpty
function from Lodash is a useful tool for checking if an object is empty in JavaScript. It can be used to check if an array, object, map, or set is empty. It returns true
if the object is empty and false
if the object is not empty.
Example code
const _ = require('lodash');
const myArray = [];
const myObject = {};
console.log(_.isEmpty(myArray)); // Output: true
console.log(_.isEmpty(myObject)); // Output: true
